Latent cold storage device

Abstract

The invention relates to a latent cold storage device with an improved structure and an improved mode of operation by means of a sandwich-type arrangement of the heat conducting elements and cold storage elements, whereby the cold storage elements made in the form of pockets containing a cold storage medium, are deformable.

The invention claimed is:

 at least one pair of adjacent cold storage elements ( 2 ) having opposed ends forming an expansion area; and 
 wherein the at least one tube ( 10 ) has a portion that extends adjacent both the at least one expansion area and adjacent at least one of the opposed ends forming the expansion area. 
 
     
     
       2. A latent cold storage device ( 100 ) according to  claim 1 , whereby the heat conducting element ( 1 ) is of a serpentine-shaped design. 
     
     
       3. A latent cold storage device ( 100 ) according to  claim 1 , whereby the heat conducting element ( 1 ) comprises at least one protrusion ( 1   d ). 
     
     
       4. A latent cold storage device ( 100 ) according to  claim 1 , whereby at least one of the at least one tube ( 10 ) is arranged separately from another of the at least one tube ( 10 ). 
     
     
       5. A latent cold storage device ( 100 ) according to  claim 1 , whereby the tube ( 10 ) is connected via at least one fixing device ( 9 ) with at least one connecting tube ( 11 ). 
     
     
       6. A latent cold storage device ( 100 ) according to  claim 5 , whereby the fixing device ( 9 ) comprises a compression ring. 
     
     
       7. A latent cold storage device ( 100 ) according to  claim 1 , whereby the tube ( 10 ) runs in a serpentine shape between at least two cold storage elements ( 2 ). 
     
     
       8. A latent cold storage device ( 100 ) according to  claim 1 , whereby the at least one heat conducting element ( 1 ) and the at least two cold storage elements ( 2 ) are connected to at least one support ( 6 ). 
     
     
       9. A latent cold storage device ( 100 ) according to  claim 8 , whereby the support ( 6 ) comprises at least one device ( 7 ) for fixing to a structure. 
     
     
       10. A latent cold storage device ( 100 ) according to  claim 1 , whereby the heat conducting element ( 1 ) is made of aluminum or copper. 
     
     
       11. A latent cold storage device ( 100 ) according to  claim 1 , whereby the pockets are made of plastic. 
     
     
       12. A latent cold storage device ( 100 ) according to  claim 1 , whereby at least one pocket comprises at least one internal partition ( 2   a ). 
     
     
       13. A latent cold storage device ( 100 ) according to  claim 1 , which is enclosed in a housing ( 5 ). 
     
     
       14. A latent cold storage device ( 100 ) according to  claim 13 , further comprising at least one intermediate area ( 8 ) between the housing ( 5 ) and the latent cold storage device ( 100 ), wherein the intermediate area ( 8 ) is made of foam material. 
     
     
       15. A latent cold storage device ( 100 ) according to  claim 1 , whereby the deformable pockets are in the form of an essentially cuboid design.
